Brief summary
The purpose of this study is to compare the performance of 4 designs of the DePuy Ultima LX hip stem in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the 4 designs of the DePuy Ultima LX hip stem and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.
Interventions
A collared non-polished/blasted finished cementless femoral component for use in total hip replacement.
A collared polished finished cementless femoral component for use in total hip replacement.

Eligibility
Inclusion criteria
Current indications for primary total hip arthroplasty utilising a cemented femoral component. These include pain, deformity and loss of function which are not responsive to medical treatment
Exclusion criteria
i) Revision Total Hip Arthroplasty ii) Rheumatoid arthritis iii) Age greater than 80 years at time of surgery iv) Age less than 60 years at time of surgery v) Previous hip joint sepsis vi) Obesity vii) Patient likely to remain housebound once rehabilitation is complete
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Stem movement measured radiographically at 2 years | 2yrs post-surgery | Stem movement was measured radiographically by comparing baseline stem position with the stem position 2 years after surgery. If migration was observed to be 5 or more mm, it was considered clinically significant migration. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparisons of Visual Analog Pain (VAS), 36-Item Short Form Health Survey (SF-36), Satisfaction, Limb Length and stem movement measured radiographically at 5 years. | 5yrs post-surgery | The following outcome measures were used; VAS Pain score, SF36 Patient reported outcome, Satisfaction, Limb Length physical examination, and stem movement measured radiographically. |
